@joe9nf@craftyguy No, this is systemd-sysext, which just layers files on top of /usr/ so these new files (usually binaries) can be added without actually modifying /usr/ in actuality
@anyDr0id@joe9nf@craftyguy Technically yes, if you made an erofs or squashfs image out of the diff from your system. Probably better to use coldbrew or a container for that.
